UNIT 2- CELLULAR STRUCTURE -BIOLOGY.
Quality content you can rely on!
Cell - Answer: basic unit of all forms of life
Centriole - Answer: structure in an animal cell that helps to organize cell division
Cytoplasm - Answer: in eukaryotic cells, all cellular contents outside the nucleus; in
prokaryotic cells, all of the cell's contents
Cytoskeleton - Answer: network of protein filaments in eukaryotic cells that gives the
cell its shape and internal organization and is involved in movement.
Eukaryote - Answer: organism whose cells contain a nucleus
Homeostasis - Answer: relatively constant internal physical and chemical conditions
that organisms maintain
Lysosome - Answer: cell organelle that breaks down lipids, carbohydrates, and proteins
into small molecules that can be used by the rest of the cell
Nucleus - Answer: structure that contains the cell's genetic material in the form of DNA
Organ - Answer: group of tissues that work together to perform closely related functions
Organ system - Answer: group of organs that work together to perform a specific
function
Organelle - Answer: specialized structure that performs important cellular functions
within a eukaryotic cell
Prokaryote - Answer: unicellular organism that lacks a nucleus

, Smooth endoplasmic reticulum - Answer: contains collections of enzymes that perform
specialized tasks including the synthesis of membrane lipids and the detoxification of
drugs
Tissue - Answer: group of similar cells that perform a particular function
Vacuole - Answer: cell organelle that stores materials such as water, salts, proteins,
and carbohydrates
Chloroplast - Answer: Organelle found in cells of plants and some other organisms that
captures the energy from sunlight and converts it into chemical energy
Mitochondrion - Answer: Cell organelle that converts the chemical energy stored in food
into compounds that are more convenient for the cell to use
Adenosine Triphosphate (ATP) - Answer: Compound used by cells to store and release
energy
Calvin Cycle - Answer: Light-independent reactions of photosynthesis in which energy
from ATP and NADPH is used to build high-energy compounds such as sugar
Chlorophyll - Answer: Principal pigment of plants and other photosynthetic organisms
Electron Transport Chain - Answer: Series of electron carrier proteins that shuttle high-
energy electrons during ATP-generating reactions
Light-Dependent Reactions - Answer: Set of reactions in photosynthesis that use
energy from light to produce ATP and NADPH
